\title{"StabilityUnion"}
\description{An object returned from a call to \link{GetStabilityUnion}.}
\section{Slots}{
	 \describe{
    \item{\code{union}:}{A numeric vector of scores derived from union counts, normalized such that 1 is the maximum attainable value. The entries
                           correspond to the positions in the list such that the
                           \code{i}-th entry contains the score derived from the union count up to position \code{i}.}
    \item{\code{unionscore}:}{A numeric vector of union scores, arranged analogously to \code{union}.}
    \item{\code{noinformation}:}{A list containing an approximation to the expected union count and -score if \code{noinformation} in
                                 \link{GetStabilityUnion} has been set to a positive integer. Otherwise, the list is empty.}
    \item{\code{decay}}{The decay scheme used for the weights, s. \link{GetStabilityUnion}.}
    
  }
}
\section{Methods}{
  \describe{
    \item{show}{Use \code{show(object)} for brief information.}
    \item{plot}{\code{plot(object, frac=1/50, ...)} produces a graphical display
    of the union count (upper panel) and union score (lower panel) for increasing list position, ranging from \code{1} to
                \code{frac*number of genes}. The \code{...} argument may be used to modify graphical options.}
